Overview

Primary hardware

Generic Edge (arm64/amd64)

What it does

Runs MediaMTX (formerly rtsp-simple-server) to fan-in cameras and restream to RTSP/RTMP/WebRTC.

Why it saves time

One binary to terminate weird camera protocols, add auth, and expose a consistent URL to your apps.

Get access

Use StreamDeploy to manage OTA updates, versioned configs, and rollbacks across fleets.
